What does a healthy community look like?

Hi everyone,

Thanks so much for your responses so far, this community is super useful.

The community I am managing is in its' early stages, and so measuring engagement is key. I wonder if anyone knows of any benchmark stats of a closed community (paid membership)?

E.g what is a healthy engagement time for new users within the first 30 days? How many times should a user be logging in? Once a week? I appreciate variables like the nature of the community and user segmentation will influence the engagement expectation, but any general averages would be great if possible.


Additionally, for engagement I am measuring:
1) Log in frequency
2) Engagement time
3) Involvement (event sign ups/comments/likes/downloads/frequency of conversations)

Would anyone suggest measuring engagement through other metrics? Big thanks in advance. Happy Friday everyone!
